This is an update to my previous review because I came here for Monday Night Unlimited Oysters for $30, aka the best $30 I've ever spent.
For $30 you literally do get all the oysters you can eat (must order in multiples of 12), and they are meaty delicious malpeque and kusshi oysters. It's not like other buck-a-shuck places where the oysters you get are tiny vestiges of molluscs meant for a tiny sea animal to eat. You get various toppings including lemon, salsa, mignonette, and hot sauce. You can also request bread which comes from upstairs (the more expensive Chase) and is warm, buttery, slightly sweet, and FREE! I also recommend the fries as an accompaniment to the oysters. They also have half price bottles of champagne/sparkling wine ($30) on Monday nights.
I suppose the value of the deal depends on how big of a glutton you are. I went with a group of 4 other gluttons and we EACH ate 48 oysters. No exaggeration. In fact they ran out of the malpeque and kusshi oysters and had to give us chef's creek oysters towards the end (also delicious). We started to feel somewhat euphoric by the end of it - Google tells me that shellfish in large amounts can be toxic, or maybe it was the aphrodisiac overload... in any case the final bill of $37 for that many amazing oysters was completely worth it and I will definitely be back!
