I had high hopes for Butter Bakery. In retrospect, I'm not sure why, as the "Butter" in its name automatically suggests a place that won't be great for vegans.
First the good: this is a cute, quaint, cozy little neighborhood cafe on a quiet street. There's outdoor seating and it's never so packed that you can't find a seat (even at brunch time on Saturdays and Sundays, when places like Common Roots and French Meadow are standing-room only). The staff is friendly and this looks like the type of place to make some cool, smart friends.
Now onto the food: the tofu scramble, in my opinion, was bland and too slight. At $6.98 with tax, it also seems overpriced. For that price, you could get tastier food, and three times the portion size, at Seward Cafe or Hard Times Cafe. There was no option for soy bacon or vegan sausage. I tried their tempeh sandwich which also fell flat for my tastes. It didn't feel fresh or light; the tempeh was too crispy and the cafe doesn't offer any vegan spreads to enhance the flavors. Compare this to the MULTIPLE tempeh sandwiches at French Meadow and there's no comparison: FM wins outright.
The food menu is available only from 8 a.m. to 2 p.m., so keep that in mind if you want to try their food. Their chai latte was decent, but they were out of rice milk every time I visited, so I settled for soy.
One final drawback: they have NO vegan desserts or baked goods at all. I found this surprising, as they do have some vegan food items, at least. Then again, as I mentioned earlier, "Butter" is the name of the place. What could I expect?
