Don't know much about Peruvian (Latin American) food but wanted to share my experience. Also tried Bo on Sat. night and will post separately.
Went there Friday night and was very impressed with the food. Based upon what I've read on the board, I tried the tacu tacu w/cilantro and fried plaintain which was enormous and delicious. I also had the aji de gallina which did not disappoint - was not overpowered by the cheese IMHO. I tried the blue corn drink which was very, very sweet but good nontheless. Whenever, I go to LA to visit friends, I always go out for Mexican - always being served super sweet drinks with the food. I'd be interested to know why this the case - for me, they could take out half the sugar and it would still taste as good.
The place had a decent number of customers so I'm hopeful that this discovery (for me) will be around for future returns.
I've eaten lunch there on average about twice a week for the past year. The $6 lunch special is hard to beat. There are about 10 basic dishes in their lunch special repetoire, and most days you have two to choose from. (e.g. beef stew, tripe stew, roast chicken, stir fried beef with peppers and onions, fried fish, pork chop).
Some of their variations of beef stew are less than stellar. The only thing I really didn't like was their version of spaghetti, which I was served after I bit into a little piece of glass in my tripe stew. But out of about 100 lunches there, that was really my only bad day. It's usually tasty, satisfying food, some of the soups (first course of the specials) are extraordinary, and there's always the hot sauce. Lots of grains, beans, meat, and rice. I keep intending to try their Lacuma ice cream, but I never have quite enough room. I'm going there right now.
I wouldn't worry too hard about the place staying in business: Tara & I went there for a late lunch a couple of weeks ago, and the place was absolutely packed at 2:30 on a weekday. There's a $6.50 lunch special that includes soup, salad, bread, entree, and rice. We both HAD to have aji de gallina, so we didn't try the special. Next time...
