Key Takeaways

Siam Green “Phrom Phong”

It is a stop for both locals and travelers, with brands like Local Boys, Auracl, and Loy Gummies on the shelves. The space has a sleek design and a lounge, and it is a short walk from the Emporium and EmQuartier malls, so it fits easily into a day around Phrom Phong.

Here’s the mini guide of where you can expect around the Phrom Phong area:

Experience Luxurious Lifestyle at High-End Shopping Malls

The Phrom Phong neighborhood is very well-known for its luxurious lifestyle as you can notice the lavish shopping malls like Emporium initially until EmQuartier opened its door just across the street, and recently, EmSphere. These specific malls in the area offer high-end fashion boutiques for high-maintenance lifestyles just like most (and wealthy) people who live in the capital have. Even the cinemas are elevated, just like the grand theater of the EmQuartier Cineart for example.

Escape Bangkok’s busy Life at Benjasiri Park

A green oasis set behind the Emporium Mall, yet visible from the Phrom Phong BTS station. Benjasiri Park was built in 1992 for Queen Sirikit’s 60th birthday. It features a mixture of art, recreation, and wellness that shows through the sports facilities like a pool and pavilions. This public park is like a twin to Lumpini Park which offers a tranquil and peaceful atmosphere, yet sits conveniently within the heart of the city.

Siam Green “Nana”

The Siam Green dispensary at the Nana location sits near Koreatown and the Asoke BTS station, so it is easy to reach. It has a lounge and carries infused beverages and edibles. The Siam Green Nana location is in the middle of a busy stretch of Sukhumvit, a short walk from the area’s nightlife.

Open every day from 11 AM to 3 AM

Address: 210 Sukhumvit Rd, Khlong Tan, Khlong Toei, Bangkok 10110 | Get Directions

Now, let’s explore what Bangkok can surprise you with around Nana dispensary:

What does Nana have to attract people?, Nightlife!

The most famous thing here in Nana that you might have heard of is probably nightlife, and as a Bangkokian, you’ve heard that right. Nana’s nightlife used to be associated with adult entertainment like Nana Plaza and Soi Cowboy. As time passed, Nana has evolved into a more lively nightlife which can be seen in the nightclubs in Sukhumvit Soi 11 like Sugar and Levels, the two most popular clubs here. Not only that, plenty of bars and rooftop bars are right next door. That being said, you can just walk from one bar, to another bar, and to the nightclub in just a few minutes.

Nana Munchies Adventures

Nana isn’t just nightlife (even though it’s a good place to party and very famous here), beyond the neon lights, Nana also offers food heaven. From street food stalls on the sidewalk to lush, high-end restaurants, Nana has a diverse array of munchies. Coffee lovers would have their jaws dropped at how many stylish and trendy cafes Nana has. Imagine those sleek minimalist interiors that would be perfect for bringing your laptop to work and sipping an expertly crafted coffee and scrumptious pastries, Mmm how could you resist?

Siam Green “Chinatown”

This location is near several of the city’s landmarks, including its next-door neighbor, the Michelin-guided Jay Fai. The line at Jay Fai is often long, and the dispensary is right beside it, a comfortable place to wait. It carries a range of cannabis products, and the Siam Green Chinatown dispensary sits in the heart of the city, easy to reach for both locals and tourists.

Open every day from 8 AM to 12 AM

Address: 325 Maha Chai Rd, Samran Rat, Phra Nakhon, Bangkok | Get Directions

Mini Tour Guide to Bangkok’s Chinatown: Highlights You Can’t Miss

Apart from the famous chef, Jay Fai, our Chinatown has a wide array of cultural sites awaited to be explored. Start with the Chinatown Gate, a symbolic entrance to this vintage-looking district. You’ll be greeted with Thai-Chinese cultural landscapes from the signs to the architectural styles of the buildings here, like the So Heng Tai Mansion in Talad Noi. And oh, speaking of Talad Noi, don’t forget to check out a street art alley in this area. We promise you (at least) one stunning picture in your camera roll taken from here is ready to post on the Instagram feed.

It would take a lot of time to name all the fun things to do here, but there are a few more that I can recommend. You can’t miss the true highlight in this area, Yaowarat Road, which quickly turns into a night market as soon as the sun leaves the skyline. Looking for cheap souvenirs? Sampeng Market wouldn’t disappoint you. Even though the price here is typically low, it’s also okay to bargain.

Siam Green “Silom” **NEWLY OPEN!**

Located in the heart of Bangkok’s financial hub, the Siam Green Silom dispensary is just a few steps from the Sala Daeng BTS station. Now it’s time for Silom, another lively neighborhood, to shine. It is a busy market with street food during the day, and it turns into an LGBTQIA+ friendly area with a lively nightlife at night.

The Siam Green Silom dispensary has a sleek, refined design with cannabis-themed artwork. The upstairs lounge is a spot to socialize or relax, with options for privacy and table service.
