I was in TPE Eva Lounge 2 days ago. I'm afraid it was rather boring and nothing special. Sitting area is quite big but food was very average. Unable to get on Wifi with my limited computer technique. I think the CX lounage in the other terminal is 100% better.
The EVA lounge at TPE T2 is poor. The only lounge worse is the China Air lounge in T1. The best lounges in TPE are SQ in T2 and CX in T1 (WIFI works in both),
