Went to El Cafe for my birthday with my wife and had a really nice experience. While it was…read morebeautiful ion the inside, we opted to sit in the biergarten because the weather was lovely. The food was EXCELLENT. We had a lovely platter with freshly made paperdele in a really good mushroom sauce, a brilliantly cooked steak, home made fries (that's chips to the islanders), nice empanada with a good salsa on top, and a REALLY good chicken caesar salad. I wasn't going to have a dessert, but then it came out, and it was fantastic. I have eaten many varieties of brownie growing up in America growing up, but this came out on top of all of them. Coupled with walnut ice cream really hit the spot.
The only bad thing I could say about this place is that the wait staff are letting down the high standard of the kitchen. Fortunately I am fairly patient, and they actually have decent tequila (i.e. NOT Sierra or Jose) so I could pass the time comfortably. Other than that, give it a go, be patient with the wait staff (or tell them to get their asses in gear), but it is all about the kitchen, and the kitchen is worth it.
