The husband & I came here for New Years Eve as a special treat. We found the Oysters Rockefeller to be very tasty and enjoyed the herb butter & bread. If we had stopped there, our review would be more positive. Our main dishes (marlin with cream sauce & grouper oscar) didn't seem worth their steep price tag ($25-30 each.) The fish itself tasted good, as did the augratin potatoes but there wasn't much flavor in anything else & the portions were small.
We are familiar with fancy small portion restaurants, but Jonah's seemed more on the average side. Next time we are in Peoria & want seafood we will go to Joe's Crab Shack where the bill was substantially less & the flavors equal or better.
