Alishan Cafe is definitely not just around the corner. However, its worth the trip out there, with a beautiful river flowing past, and a large park to stroll around in, see the horses and generally relax, or if you are looking for 30 mins good exercise, then Hidaka mountain is good for an easy hike.
The food is vegetarian, some vegan, and all delicious. Its not Gordon Ramsay Hyatt Regency style fancy food, but down to earth wholesome well rounded meals.Not boring in any sense, and lunch sets have soup, salad (with amazing home made dressing) usually rice and your main event.
My favorite is the Vegie Burger, or Bagel. Both are awesome. I mainly prefer bread to rice, but im partial to the Mabo Dofu too. im not such a cake person but banana cheescake is hard to pass up, and you have a good excuse if youve climbed the mountain before lunch.
All in all an awesome experience. Super friendly staff and lots of cute kids exploring the area, as lots of mothers with young kids seem to love it there.
I saw a review with concern about eggs. In my opinion eggs are ok veg food, but its up to you. They are willing to accommodate any variation of food dietary needs. You just have to ask.
Cons: Far from city (also a pro)
