Market of Choice, Burlingame
The danger zone, for me, is towards the cash register. The beer case—well, no one is going to confuse it with Burlingame Grocery—but they hit all the high points, both locally, from the Northwest, from the States, and internationally. The guy stocking the beer case is a font of beer knowledge. The wine section is a bit bigger, but I get the impression that it too is tightly edited. Then you have to walk past the cheese case, the wood-fired pizza oven and sandwich stand, the sushi makers, the salad bar, the deli case...
In the name of science, we tried the pizza by the slice. Perhaps there's some sort of perfume in the air that makes everything there exquisite, but for grocery store pizza, it looked really good, and it was really good. Now, it's got nothing on a good slice from Escape or Hot Lips, and it's nowhere near the league of Apizza Scholls or Ken's, but it hit the spot. And for $2, a reasonable snack.
I suspect if you regularly shopped here, it would add up. But the beer prices are competitive, and stopping in for beer, milk, and deli stuff, it doesn't seem so much more than any place else.
