Some good reviews. I enjoyed the Gallery as well and find it well priced and a relaxing place to go. Well Unless you go when it's free on Wednesday night.
Anyhow some people have nitpicked about the rules. I found this silly since the reason your asked to check certain items is to protect the priceless art work. You may wonder why your coat has to be checked or an umbrella, but think if your umbrella was to mistakenly open while your in the gallery and damge a piece of art work. Not saying you'd make such a mistake but what if someone ran into you. Same can be said for drinks, like bottled water or anything else including food. Your wet jacket might rub against something. Your trench coat may snag something.
All the rules are there for a reason.
The new layout is beautiful. But I can see how some people may get lost or miss out on certain area's.
