They offer vegetarian lunch the last time I was there. I think it cost $8.00.

Pets aren't allowed in the temple. Thank you. You may find more visiting 101 information here

No problem ! But remember that you have to take a lot of steps before you reach the temple.

Temple is opening 9-5 everyday except the Museum is closed on Mondays.

On their website, it states that one must dress appropriately, i.e., no sleeveless shirts or no short shorts or cut-offs. However, when I was there I saw a few women wearing shorts and tank tops. I even saw one woman wearing see-through top. So, I suppose it all depends on the discretion of the person at the front of the temple when you get there. In other words, wear a pair of jeans and short sleeved tee just to be safe (depending on California weather).

I'm pretty sure that if you go on their website and call them, you would be able to obtain the detailed answer to your question. I only visited it once and I don't know what their gift shop carries nor am I familiar with their store policy.

I am do not live in California, so I am pretty sure that if you go on google search for Hsi Lai Temple's website, you will find all the answers to any of your questions and you can even call them directly. The phone number can also be found on their website.

There are stairs and steps in the temple but most of the temple grounds are wheelchair accessible with minor slopes to avoid the steps/stairs.

$8, opens around 11:30am

Yes, they do offer tours for a big group but you must make a reservation in advance. Please visit their website for reservation and details.
