I've been here several times. A couple times I was lucky and only had to wait 30 ish minutes, once I went near by and grabbed a drink while I waited for 45 mins, two other times the wait time was over an hour and we gave up.
Every time I've eaten here, the servers are helpful and friendly and the food has been fantastic. The Ceviche and eggplant are my favourites. I suggest filling up on the mains - the yam dessert wasn't my cup of tea.
For two people, it comes up to about $100... which is quite pricey for what you get so I probably can't come here as often as I'd like.
