Sepal is great, though the location doesn't lend itself to easy parking if you're going at night. The ambiance is quaint and friendly. I can't think of anything on the menu that is less than stellar, though I don't eat meat so I couldn't comment on any of those dishes.
The last time I went there the credit card machine wasn't working properly and no one had notified us prior to sitting down. Luckily enough we scraped up enough cash to pay, but I was a little put off by that.
Best bests are the lentil soup, fattoush, hummus, baba gannouj, and their falafel!
