I had lunch there with the family recently, a few days after they had opened. Tuckeria, inspired by the taquerias (taco shops) found in San Francisco's colourful Latin district 'The Mission', serves Mission style Mexican with an emphasis on fresh and healthy.
They have the standard Mexican menu: burritos, soft tacos, quesadillas, and enchiladas. You can choose your own filling (steak, beef, chicken, chorizo, grilled prawns, pork, or beans), add beans and/or salsa, and any extras such as sour cream, jalapeños, or Mexican rice. Extras are an additional cost.
We ordered a beef burrito, chicken tacos, and some cheese quesadillas for the kids. While the food was fresh and flavoursome, it wasn't the best Mexican food I've eaten. But keeping in mind that Tuckeria is 1. a fast food restaurant and 2. they had only been open for two days, I would try Tuckeria again.
There were a couple of standouts on this trip: the Chilli Cheese Fries and the Pico de Gallo Tomato Salsa. The children demolished the chilli cheese fries and I loved the salsa. I haven't tasted salsa like this since my last trip to Mexico. Unlike anything you will find in a jar, pico de gallo is made fresh from diced tomatoes, red onions, lime juice, and cilantro (coriander). You can opt for hot, medium, or mild. If the salsa isn't spicy enough for you, try the hot sauce. There is a bottle of it on every table.
