The Trinity City Hotel

You're steps from Trinity College on Pearse Street, and hunger strikes at 2am after a proper session. Most places have long since shuttered, but this hotel restaurant keeps the lights on around the clock. The dining room feels more business hotel than boutique, but when you're desperate for actual food instead of another chipper, it'll sort you right out. The menu skews international with decent steaks, pasta that won't offend, and breakfast served whenever you need it. Staff are sound and used to dealing with everything from jet-lagged tourists to locals stumbling in after the pubs close. It's not going to change your life, but sometimes you just need somewhere reliable that's actually open when the rest of Dublin has gone to bed.
