I-Sa-Nu at Ainu (B320)

This new Japanese restaurant and bar is inspired by the historical indigenous people of Hokkaido of the same name. The concept shines through in the signature cocktails, too. This smoky long vodka-based drink also comprises Genmai tea (green tea with roasted brown rice), sweet vermouth, green tea syrup, homemade pandan syrup and lime juice, topped with khao kua (crushed roasted rice). If you're wondering why this main ingredient used in Isaan food is added here, that's because Hokkaido is also in the Northeast of Japan. And it matches the aroma of the Genmai tea perfectly.

Dusk Rosita at Dusk Thonglor (B340)

This new rooftop bar on Thonglor Soi 13 takes its craft cocktails seriously. The most interesting has to be the Dusk Rosito, which is like a spruced up Hendricks cucumber with pomegranate, jasmine and homemade syrup to add even more freshness, while a little egg white creates a foamy texture on top.

Thonglor Soi 13, 096-860-7690.

Shoshoni at Jubei (B220)

This Japanese Izakaya is not all about draught Asahi—their signature cocktails are pretty tasty, too  good priced too. Shochu and sake are the main spirits, here. Try the Shoshoni, a negroni-inspired cocktail that uses shochu instead of gin, mixed with Campari and vermouth, and topped with Campari foam (made with espuma) and orange zest.

Survival Kit at Bonfire (B550)

This rooftop bar at Rainhill community mall carris a bit of an adventurous camping theme, which is also reflected in the cocktails. Created by Niks Anuman-Rajadhon (Teens of Thailand and Drinks Academy), the Survivors Kit comprises two cups of vodka-infused pomegranate tea mixed with honey, lime, St. Remy cognac, wild berry syrup and Amaro peach liqueur, accompanied by almonds, rosemary, mint, orange, jelly and apple inside a metal rice cooker.

Tid Koh at 80/20 (B220)

This brand new Thai-Western restaurant on Charoenkrung Road not serves delcious food list, but also does inventive, Thai-twist cocktails. The list focuses mainly on local spirits and ingredients; don’t miss the Tid Koh (Chalongbay rum, sugarcane juice, coconut juice foam topped with chopped kaffir lime leaves).

Customized Coffee Cocktail at 722 Craft Experience

Ekkamai’s newest rooftop bar serves a range of craft beers, but the guy behind the bar also mixes a fine customized drink. On our last visited, we requested a cocktail made from beer. The guy picked Hamer & Sickkle imperial stout as the base where he topped up the stout’s coffee aroma with Kahlua and syrup, then garnished it with raisins and a cinnamon stick.A potent yet refreshing mix. Do note: this dirink is not on the menu.
