Mister Ed

Interesting building with a couple things you can do inside. It costs 5 pounds to go up the stairs to see the camera obscura room but the weather needs to be sunny in order for it to work. The view is good though, the downstairs stairs to the giants cave is fun for kids, not so much if you're tall as it's narrow and the rock ceiling is low in places. Still it's worth doing and the experience is fun.

Make sure you pay attention to the street parking signs as not everywhere is for public use, there's quite a lot of resident or permit holders only spaces. Prices are 1.50 an hour, it's max 3 hours before 5pm, 4 hours after 5pm. You only have to pay between 9am and 6pm monday to Saturday.

OK Chinese restaurant, it's not that big and it gets busy, best to reserve a table if you can. Food is OK in my opinion, service is very good, they serve a variety of dishes including home style dishes. It will depend on what dishes you order, but the dim sum was poor.

Small roller coaster, aimed at younger kids, I think this is more appropriate for 7 and under kids, or if your kids are just over the 117cm height restriction on the nickelodeon steak ride. It's not as fast, the drops are not as extreme so it's safer for younger and smaller kids.

Excellent kids theme park, definitely recommended for younger kids. Most of the rides should be suitable for 5+, some will require an adult to accompany them. There are height restrictions do you need to be sensible. Staff are friendly, and accommodating. Nickelodeon land is included in the entry to pleasure beach. The nickelodeon streak may not be suitable for younger, or smaller kids that just meet the height restrictions as they will get thrown about a bit. My youngest who was sat with me, his head was jerked violently side to side, and he would hit my shoulder a lot so be aware that this ride may not be suitable. This and the airbender one are the most extreme rides they have for kids. The blue rider one should be OK as it doesn't go as fast, or have much elevation drops.
Note that this part of the theme park closes at 5pm, unlike the rest which closes at 6pm.
Highly recommended.
