Pancake Bakery: Obviously incredible pancakes and poffrijes, if not a little overhyped and overpriced. The pancakes are wider than your face, and there's a huge vat of molassesy syrup that you can drizzle and/or scoop onto your doughy delight of choice, which is fun and interactive.
Pancakes Upstairs!: Another place, another pancake, but the ambiance here is more traditional Dutch and therefore a little more authentic of an experience. Go at an odd hour during the week, or you'll wait forever to be seated.
Winkel: Decently priced authentic Dutch food, plus world's yummiest slice of apple pie. Not the friendliest of staffs, but that's just kind of Europe.
De Bolhoed: Insanely delicious vegetarian place on the Prinsengracht. Get their vegan meal of the day. They get bonus points for having a cafe kitty.
Kookoellektief: Another awesome, vegan-friendly place! Their menu is limited, but continually changing and so healthy-yummy.
Singel 404: The best sandwiches you will have in your life. In the words of the great Cait Dowling, "#44 changed my life." Truer words have never been spoken.
Broodje Bert: Super delicious sandwich shop for basically no money. Even their side salad is good.
Vinnie's Deli: World's cutest lunch spot. Think light, bright, with all vintage furniture. Delish open-face sandwiches, excellent vegetarian options and a really friendly staff. A little on the spendier side if I remember correctly.
G's Really Nice Place: Easily world's coolest brunch spot - Drake & The Weeknd playing, menu formatted in sexual innuendoes, trendy/urban decor, and food that is to die for delicious. Probably my favorite food spot in all of Amsterdam.
De Lastse Kruimel: The cutest sandwich/pastry shop in Amsterdam, right around the corner from UvA's Oudemanhuispoort (OMHP). Perfect place to pick up a slice of quiche or apple pie in between classes.
Kapitein Zeppos: Charming little gem tucked away in an alley very near OMHP.
Baut: Located right next to Trouw, this bar/restaurant has an equally cool vibe inside and serves really yummy open-face sandwiches for lunch.
Sampurna: Excellent Indonesian food, which Amsterdam is known for. Also decently priced, especially if you split a meal.
Cafe Bern: If you're craving yummy Dutch-French fusion fondue, this is your spot! Go on off-peak days/hours, because it's really popular.
