Cafe Neon is a relatively new place on the corner location of the old Cafe Proust at 1799 McAllister St (cross street Baker). We went last night for a cheap, quick dinner and I was impressed.
The interior is pleasant - high ceilings, walls of windows, comfortable big chairs and tables. They play mellow reggae at a non-intrusive volume. On nice days they pull back all the windows. The menu included nice renditions of burgers (with chicken, turkey or garden burger option), sweet and savory crepes, huge salads, and breakfast. You order and pay at the bar, and they bring you your food. They also have beer on tap (including Fat Tire) for $3.50 a pint, I think (bottles are $2.75) and hookahs (though no one was partaking at the time).
My friend had a huge chicken breast burger with avocado, bacon and swiss, with thick steak fries. I sampled it and found it very tasty. I had a delicious, gigantic spinach salad with beets, walnuts and feta in balsamic vinaigrette. It came with baguette. I believe both dishes were $6.50 - same price for lunch and dinner. That same salad downtown would have cost upwards of 10 bucks for sure. Usually I complain that I dont get enough greens in an entree salad, but I had no such complaints here. The other entrees around me looked enormous and satisfying. I will definitely be back.
