I would add Butter, (see this thread [Butter - breakfast and lunch cafe a new entry to the Taipei eateries scene since this thread was started.
I had brunch there again last weekend. A three-egg omelette that comes with coffee, juice, bacon, hash browns and toast (am I forgetting anything?) all for about NT$130 (or maybe $160, I forget because there were three breakfast specials and I mixed and matched adding some sausage for a small extra charge.) Anyway the food was declicious, nice fluffy omelette, good western-style bacon and sausage and they even have multigrain toast now.
Their coffee is better than starbucks, and even better, the atmosphere is great for brunch; nice and relaxing, a description you wouldn’t necessarily expect for a place in this thread. I was stuffed and satiated when I left. Go now before this place becomes the new popular spot and you don’t have to wait for tables.
