Bumpy's is a pretty awesome little cafe. It's a little hard to spot the first time (about a half block south of 10th Ave on 8th St, after the alley) but once you know it's there you just want to keep going back.
Their muffins are phenomenal, and they have flavours you'd never see anywhere else. Forget boring blueberry or carrot bran - they combine all these ingredients such that you have a tough time picking just one.
The coffee is yummy! I've never had one that I didn't like. I'm generally a latte person and an indication of a good one is that I don't have to add sugar - no sugar here! They also sell JJ Bean coffee, in case you've gotten addicted to it while in Vancouver.
I've had one of their breakfast paninis and it was also yummy. Some of their soups and specials sound amazing but I'm usually only dropping by for a coffee. Would like to stop and have lunch there someday.
Worth a visit!
