還沒有去吃過，標記一下，下次一定要試一試。

如果你搭乘捷運交通系統，需轉換一次車輛，大約需要40分鐘的時間

There is no dress code! However I recommend you wear presentable shorts as you are in religious premises!

Sorry Natti. I am not sure.

Yes, there are 2-3 a few blocks from Longshan Temple on the left, right, and behind. Can't remember their names, but one of them is the famous 'Snake Alley' night market.

No admission fees for any of the temples we visited in Taiwan

Since you will have nearly eight hours on the ground, five hours is a realistic estimate for time you could afford to be away from the airport after clearing customs and allowing time to get back in to check in, go through security and clear passport control. The Long Shan Temple is certainly worth seeing. An English speaking guide will make the visit much more interesting and enjoyable. You'd likely even have time to walk around the nearby shopping area before heading back to the airport. However, I caution you to take a taxi from and to the airport rather than the "airport bus", which can take two hours or more each way from the airport into the city area near the temple with multiple stops in between (vs 45 minutes to an hour in a taxi, maybe less if traffic is light), and riding the bus requires knowing where you are going (where to get off the bus and then get to the temple -- don't count on the bus driver understanding English to give that advice). With the taxi, you can take a print out of your destination address in the local language as well as English (wouldn't hurt to include a picture) and the driver will get you there as quickly as safely possible.

Yes it has a man made water fall, nothing special.

So sorry to post this answer. Been there last Saturday. Observed no visible direct entry into temple for wheel chairs. Entrance to the temple is by the 2 side trap doors at the extreme left and right of the main gates which you need to walk over them. There is a side entrance which is accessible by staircase. Within the compound there is no visible access for wheel chairs to move to various section of the temple
