Erin's Snug is fine; it's not amazing and it's not bad. It's simply mediocre. I've been to Erin's Snug a few different times for lunch, dinner and drinks. Every experience I've had there has been the same: the service is sort of slow but okay, the food is basically average, and the place is always extremely empty. I've gone during off hours and peak restaurant hours, and the restaurant is always empty!
The Irish theme/decor is cute and visually appealing, and I think that's the winner for Erin's Snug. The food could be the winner if it were better-seasoned and specifically if the calamari were better-fried and crispy. Soggy calamari makes me sad!
Erin's Snug isn't a place that I will go out of my way to visit, but if someone invites me to go to Erin's Snug, I'll definitely tag along.
