Unless the "world famous tapa" costs P275. Nope! No can do, sir. It's just too much for a glorified breakfast meal. So we ended up ordering...
Silver Dollar Pancakes Breakfast (P210) + Hash Browns (P35) - ★★★☆☆
Grilled Chicken Salad (P250) - ★★★★☆
Bottomless Iced Tea (P105) - ★★★★☆
So! Gram's Diner = food was generally okay but a bit expensive, aircondition was weak during time of visit (lunchtime + floor to ceiling glass windows so it was uber warm inside), and service was a bit slow (not the food, but the refilling of iced tea LOL). The place was packed toward the end of our stay so it was good that we were there as early as 11:30am. But overall, we still enjoyed our time at Gram's Diner thanks to the travel stories shared over jars of iced tea :)
Total cost for 2pax: P767.95 (inclusive of 10% service charge)
