text: When we first moved to Arizona we lived in Ahwatukee and Abacus Inn was on restaurant of choice on Elliot and 48th.   Fast forward 20 years and one pops in closer to us so we thought we would give it a try.  \nI liked it, she didn't.  It wasn't the same as we remembered.  Maybe we aged.  Maybe they did.  The place is tiny and packed.  There appears to be a brisk take-out business happening.   The menu appears to be \"lite\" on menu options and not like other Chinese joints where there are endless pages of options.  \nWe preferred Shanghai on 67th and Happy Valley (in the Fry's shopping Center) as our favorite Chinese in the Northwest side.  \nThere is some serious commentary needed and it's how these Chinese restaurants seem to make take out orders, over in restaurant orders.   They must teach them that in Chinese Food school but I have seen full packed restaurants of people waiting up to an hour + for food, while the take out is brisk.  I have seen people walk in, order takeout and then sit and eat it whiles others wait.   I'm not sure why they do this, but all Chinese joints seem to partake in this mistake.
