My girlfriend and I just went to Café Lyon, a new little café that's taken over the old location of Jucy's on the corner of Miles and College Ave., just north of the Rockridge BART station. It's a tiny, but simply elegant cheap little joint.
We each had a $6.00 ham and cheese panini, which came with very good ham, but the cheese appeared to be cheddar (not very French), grilled on a croissant. It came with a small spinach salad and a sliced fig (a nice touch).
There were two other fellows eating lunch at the table adjacent to us, and they appeared to be enjoying a beet salad with goat cheese.
The lunch menu was simple and pretty cheap, all things considered. The most expensive thing on the menu is $6.50 -- other options include a soup, quiche of the day, a baguette sandwich, and a couple dessert items.
The waiter told me that the café had been open only a month, and that he'd been employed for only about four hours.
There are loads of power outlets along the walls, but no WiFi as of yet. There was one guy who said he could get a weak signal from the building.
All in all, I'd go back and would try the quiche and some of the other things.
