I've stopped here several times on my way to go shopping at the big market just north of the US consulate. The food is always pretty good. Nothing mind-blowing, but there's always a nice variety of dishes, from greens to pumpkin to curries to fake meats, all served with black/purple rice. A plate of rice and 3 vegetables will cost you 35B; an extra deep fried bamboo and mushroom cake will set you back another ten but is well worth it!
The market across the street is also well worth recommending! Coconuts for 10B each, roast sweet potatoes, fresh avocados, cashews...all sorts of great veg treats for prices far cheaper than you'd pay inside the city walls.Pros: Dependably good food, quick service, Nice, shady outdoor dining
Cons: Ordinary (but in a good way!)
