The CocoaHeads NL meeting will be held at University of Utrecht on the campus, de Uithof. There are very regular busses to the Uithof from Utrecht CS (the main train station). For example, line 12 departing from Platform C3. Utrecht CS is currently undergoing some major renovation. You may want to take this into account when plannig your journey.
Dinner, drinks and reception will be from 18:00 to 19:00 in the Educatorium:
There is a large cantine on the ground floor of the Educatorium – you can't miss it. We will be in the Balkon Pi. Look for the hidden staircase in the corner of the cantine.
The talk will be between 19:00 and 20:00 (approximately). The talk will be held in a separate room, 033 of the Marinus Ruppert building. To find this room, leave the cantine and keep going straight on. You will enter a long hallway with many large lecture rooms on your left. The room 033 is towards the end of the hallway on your right. Follow the signs.
Afterwards, we'll have some time for discussion and drinks. If people are keen to stay on till after 21:00, there's a nice bar (The Basket) right next to the bus stop. I'd be happy to point it out to you.
