The best time to go to Mykonos if you’re looking to party (similar to Ibiza) is from June – August.

Things to See:

Mykonos Town (Chora)

Little Venice

Matogianni

Delos (Day Trip)

Platis Gialos Beach

Armenists Lighthouse

Restaurants:

Interni – Mediocre food, but turns in to a big club (like Bagatelle) and is fun
Kikis Tavern
M-eating
Spilia – Pretty restaurant on the water, make reservation in advance
Zuma (food is pretty good at every Zuma, but this place is better than most, great service, exquisite location)
Kalita
Byblos
Coya – good Peruvian, it’s a chain, but worth going to if you want to change it up from Greek food
Nikolas Taverna
Tasos Taverna

Beach Clubs:

Nammos – good for lunch, there are two sides, a just lunch side, and a lunch side that turns in to a party

Scorpio’s (Fun parties here, good on Sunday, Tuesday, Thursday). You can come during the day, or come at night for the parties. If you are dressed for beach you will be asked to leave. Flex is to come at ~5PM before it turns in to a party (dressed nicely) and you should be able to get in without buying a wristband or table.

SantAnna – Cool club, pool/water surrounds the main DJ Stage

Principote

Alemagou – (Fun for parties, good on Monday and Wednesday)

Bars:

Scarpa
180 Degrees Sunset Bar
Vencia Pool Bar 
Remezzo
Skandanavian bar – trashy but kind of fun sometimes

Clubs:

Moni – Most exclusive club in Mykonos, requires a 1:1 guy gal reservation (or not if only girls).
The Void
Cavo Paradiso – really big concerts here. Pretty sweet in a rock formation

Lodging:

Myconian Ambassador

Blue Greco

Cavo Tagoo – If you want to blow money….

Porto Mykonos – I actually really liked this place on my second stay as it’s walking distance to Mykonos town, not as loud, great service.

Staying in Elia Beach is cool too, pretty but 30 minute ride from everything (which is normal)
