Av. Seminario 96 (corner Rancagua)
This is a very small restaurant, located just 6 minutes away by walking from El Patio Suizo, you can't make reservations because is SO LOVED by everyone that is always full, so you have to know forehand that if you find a table when you get there, you're lucky, otherwise, you need patience to wait. They have actually 2 restaurants, one Olán is at the right hand side of the street and the other one at the opposite side of the Seminario Ave. Both are known, delicious and full.
The prices are really convenient and the food is very tasty. The dishes are more than enough and a MUST TASTE is their Pisco Sour, is great!! Ceviche is wonderful! the Pepper Steak with rice is marvellous, but the the only thing is that the restaurant is always so full that the service needs patience since they're a bit slow. But after all... we're having vacations! we're having fun! there's no rush!
We totally recomend it!
Atmosphere: totally casual
Prices: convinient
Opened from Mon to Sat lunch and dinner

Update (May 30th, 2010): Olan is still a very good choice, prices went a little bit up, like everywhere else, but food is still great and dishes are very big!
