The new breakfast and lunch branch of Dona Tomas has opened in the heart of Fourth Street in Berkeley. It's a bit hard to find: it occupies part of the space that was the vegetable store a few doors down from Cafe Rouge, not on Fourth Street itself, but along the parking area opposite Sur La Table.
It's a pretty, cheery space open to the street and the wine shop and food store which flank it on either side. There are about a dozen tables, and seating at the counter. The menu is very simple: Mexican breakfasts until 11:OO, then various tacos, tamales, a ceviche and a few other dishes. We had the ceviche and a mushroom quesadilla, both of which were well up to the standards you'd expect from Dona Tomas. The quesadillas (two) were $5.95 and distinctly small - my only warning about this place is that you should probably order a bit more than you might otherwise because of the portion size.
There are Mexican sodas, and sauces and tamales packaged to take home. (Most were sold out by noon on Saturday, suggesting there are a few kinks to work out at the outset.)
This will be a really good addition to the local dining choices. My guess is that it will be mobbed when word gets out, so this is the time to go...
