Firstly, this place isn't nearly as bad as some of the comments make out. Well, not in my experience anyway.
I'd recommend the potatoes cooked in tomatoes, cumin and onions. Vegan and really tasty. Ordered medium spice last time and it nearly blew my head off, so will go for mild next time. I don't exactly have a good spice threshold though, so bear that in mind.
Easy place to get to, with entrances on both Soi 11 and 11/1. Fairly cheap, not by Bangkok standards, but way cheaper than anything back in England would be for me.
Overall I'd recommend this place if you're within 3/4 BTS stops away, but I wouldn't say you should go out of your way for it.Pros: Tasty curries, Excellent breads, Good location
Cons: Quite a long waiting time for food
