What character is 刄 + 丶? Here's a pic I took in HK today

What's the 刄 + 丶 char? In

堂飲2 xxxxxxx 28元

I'm guessing its similar to mainlands 两, for alcoholic drink sizes.
I tried zisea &amp; zdic to no avail...
edit: is it this: ? http://www.zdic.net/z/84/wy/20090.htm
It's the closest thing I can find
Yes, it is indeed a variant of 两. You can see it listed here in the Dictionary of Chinese Character Variants 《異體字字典》:

As for why they've chosen to write it this way, I'm not sure.
