Thanks for writing about these two establishments. I decided to eat there after searching for ideas on the board.
We arrived at 9:30am on the Friday after Thanksgiving. The donuts at Bob's were unfortunately not very fresh (they were old enough to at least be room temperature) but otherwise quite good. The beignet was strange--more like a powdered sugared pillow of King's Hawaiian Bread than a fried pastry--but still pleasing. The plain old fashioned was crispy, tangy, and not too sweet. The favorite though was the cake donut with a sugar glaze and coffee-cake-crumb crust. Delicious.
The best part of Loteria were the tortillas. We sat at the bar and watched a woman press each tortilla by hand and cook them on the grill. The corn tortillas puffed up in the middle, which I've only ever seen in flour tortillas before. Light, warm, corny, delicious. The slightly spicy cochinita pibil was the favorite filling, the pollo en mole negro a close second, but the tinga de pollo was very disappointing (watery and bland). We also had sopes (not as fresh and good as the regular tortillas) with pollo en mole negro and pollo in a peanut mole. The peanut sauce was very rich and nutty, good only in small quantities. Sides of black beans and white rice were also good, but next time I'd skip those for more tacos. Man, those tortillas.
Unfortunately I was unable to try Guelaguetza and La Super Rica as I had planned.
