I looked at the RR menu online, and this is the listing for Appetiser D'Lirrah for Two -
Our Dalkey Battered Sausages, Georges Bank Scallops, Guinness Glazed Ribs, and Chicken Lickin' Skewers $26.00
This looks like a new combo plate of some of its best appetizers. I've had the Dalkey Battered Sausages and the Guiness Glazed Ribs, and they're great! We get them just about every time. The sausages fairly mild with a batter coating and a great mustard dip. The ribs are a bit sweet with a hint of rosemary.
You might want to look for images of the individual items on the Food Porn thread to get an idea of what they look like, and hopefully someone whose been recently can let you know about the portions.
BTW, congrats on your upcoming wedding.
