the carne asada with fries and the jalapeno (cannot find a tilde on my keyboard)  poppers are quite ok in Margarita storm 

went there once and I was not impressed at all!

The Spotted Pig: Tex-Mex at Its Finest in Bangkok’s Silom Area https://www.globe.co.th/eat-drink/gourmet-guide/the-spotted-pig-tex-mex-at-its-finest-in-bangkoks-silom-area/

The Spotted Pig is a Bangkok restaurant specializing in Tex-Mex cuisine, centrally located on Silom’s Soi Saladaeng 1.
The casual, all-day dining venue serves up authentic Mexican fusion dishes in a large renovated shophouse, first opening to the public in April of 2022.

They have also opened a branch at the Food court of Emsphere (a new big shopping Mall near BTS Phrom Phong, houses also the IKEA Sukhumvit Branch), their menu looks similar to the Saladaeng brach, but be advised here you will have a 'fast food' ambiance including food served on plastic plates !

I have been to both branches (end of 2024) and liked the food there so you might give it a shot if you are around one of these !

See below the pics of the Saladeang branch, for directions, menu and reviews see Google Maps etc !

Hey @Genghis, I would recommend Molino on Soi 11. I went there once last year for dinner, excellent food and cocktails.

I have been to the mexican restaurant in Terminal 21, a bit more relaxed than the tex-mex takeaway style.
