If you're in Izmir, and you haven't seen many other museums with collections of Greek and Roman antiquities, then I guess this would be a pretty decent museum. But for me, it didn't really offer anything that I hadn't already seen in other museums. It is a small collection, but nicely laid out. The pottery seems to be mostly in chronological order, so you can see how things evolved. The statues are illuminated by motion-sensitive lights. Which at first was kinda fun, but after so many of them didn't work, it became a bit frustrating. There's some sparkly jewelry and some shiny coins, too. Information is provided in English, but is mostly limited to just the titles of the works and/or where they're from.
If you go, ask at the front when you buy your tickets if they have any of the (free) Izmir books in English. The books has pictures and descriptions of some of the items on display, as well as information on other museums and sites in Izmir.
