I was there last night! Thanks to the lovely respondents from my request I had pre Other Art Fair dinner at Skaf’s on York. It was quite good - we shared baba ghanouj, spicy garlic potatoes, and a CYO kabob plate with lamb and kafta. With our drinks and tip it was $35/pp.
My friend got us the tickets so I don’t know where the park and ride option pick up was. I can tell you street parking is quite difficult, and the immediate food options are limited.
Other Atwater lunch options I’ve had recently and really enjoyed - the India’s Sweets and Spices.
