I didn't eat here so I can't fully rate it, but I did go in and ask some questions. It sounded like the waffles were the only safe option on the menu. It's a very small kitchen and the rush of cross contamination for any other menu items seemed high. I wasn't in the mood for a waffle, so I didn't eat here that day.
Their online menu for Nectar Cafe in Hollywood doesn't seem to state it like the menu for the location on Woodstock does, but all their waffles are gluten free and vegan. Last time I went there I had the potato waffle. It was good though a tad too salty for me (in the way of, hey that's too salty, gimme another bite). Space is small. IIRC the biggest table seats 4. It's primarily a coffee house.
