Fun spot to go to for some pretty decent Thai food! Cool atmosphere and space, and nice service. Worth noting you can only pay in cash which is a bit odd.

Really delicious Thai food! BYOB and cash only. Staff are super friendly and will explain all the dishes, including how best to enjoy them.

The food is phenomenal, this was my first time trying Thai food and I was blown away! The flavours are amazing, the servers come briefly but they were nice. The atmosphere is very lively and loud, it is a bring your own drink restaurant which is so cool!

What a cool little restaurant with extremely sweet and lovely owner. I like the decor a lot. For those two reasons, I give it 5 stars. Food wise, it was fine. My dish was too spicy so she kindly replaced it with a new dish with less chilies. Thanks for that. The prawns were very big and plentiful. I’m extremely happy with the quantity of it. The taste is not too authentic but suits most people’s tastebuds.

Great dining spot with friends during the summer - penalty of outdoor seating and fairly airy inside. Great starters (we shared some between the table), less keen on my main but I’m not a huge fan of Thai food anyway so was to be expected. BYOB and cash only, so worth visiting an ATM first

This Thai restaurant is so good! The food arrived quickly and is very fresh and authentic and lots of it! We had a great table down stairs where it’s a bit quieter as very busy upstairs. The staff are so kind and work hard. Cash only and bring your own alcohol.
