Food wise, I ordered the Shawarma sandwich. It was bigger than any other gyro or shawarma sandwiches in the Oakland area at about 10". The meat was decent, and I could definitely taste lively veggies inside. I liked the parsnips but thought there was too much tahini. It was also filling which made it a decent deal in Oakland for $7.22.
I liked how the cashier (I am presuming the owner) knew his regulars and was friendly. I didn't like the wait time for a shawarma sandwich. A twenty-plus minute wait for an item without unique ingredients at a place that wasn't busy is too long.
I'd rate Nellie' three and a half stars, but I cannot thereby I am rounding up to four because I think they offer the best value for Gyro and Shawarma sandwiches in Oakland.
