I eat here fairly often, because I enjoy spicy Thai noodles, and I almost always order the See Yew with tofu, which is delicious. What I feel sets this place apart is that I can freely ask for "no fish sauce" (since I am a vegetarian), and they happily accommodate. I understand that there are probably more authentic Thai places out there, but not all of them are so understanding of my desire not to consume fish products.
I also like that it's BYOB, and I don't mind the cash-only rule. Every time I've gone, they've been super chill about splitting the bill.
A couple downsides (that keep it from getting 5 stars):
1. They don't allow for call-aheads or reservations and it can get pretty busy. I hate waiting (sometimes the wait is over an hour) so I only eat here for a late lunch (like 2ish).
2. The spice level is somewhat inconsistent. I tried every spice level up to 4 before finally deciding on 3. Some days that 3 tastes more like a 2, and others more like a 4 or 4.5! Just a heads up so you don't accidentally order something too spicy to eat.
