The Berghoff is a great Chicago restaurant. The food is good and plentiful. The service is excellent. Your water glass will be refilled all the time without your even noticing. It's perfect for lunch or dinner, from meeting with casual friends to a formal celebration. And the prices are amazing considering it's downtown - a perfect place to take a big group of people because you'll actually be able to afford the bill. The cost will vary greatly based on what you order and whether you have dessert, drinks, etc. The dessert is worth trying to.
Also, as a quaint aspect, next door to the main restaurant is an old-fashioned (just because it never changed) stand-up deli - you can get sandwiches made quickly - still German food - and either take it to go or eat it standing up at high tables.
