We will be staying in the Schwabing area and would love any casual
restaurant suggestions you have in that area or other areas that you
think a 14 year old might enjoy.
When do you arrive? Till July 21, 2024 the Tollwood Summer Festival takes place in Olympiapark. It includes a large number of very diverse food stalls from all over the world. It'e Always worth a visit.

If you are already in Munich on July 20, there will be a big fireworks display in the Olympic Park, called Midsummer Night's Dream.
It is a choreography of music, small firework effects over the Olympic Lake and a high firework display from the Olympic Mountain.
You have to pay admission to see the whole event, but you can see the high fireworks from everywhere near the Olympic Park, e.g. from the Tollwood Festival.
The Leopoldstrasse in Schwabing between the subway stations "Münchner Freiheit" and "Giselastrasse" is very lively with a large selection of restaurants, cafes and bars.
There are also many restaurants in a 200 meter radius around the intersection of Herzogstrasse and Belgradstrasse.
On the way to the Olympiapark you could visit the "Hofbräu am Oberwiesenfeld", a good Bavarian restaurant.

A visit to Munich should always include a visit to a Munich beer garden (weather permitting).
And of course you can also drink something different than beer. In a Munich beer garden you can bring your own food, but of course you can also buy hot and cold meals there. A typical small meal in a beer garden is Obazda (a Camenbert-based spread) with a giant pretzel (Breze).
There is a beer garden at the Viktualienmarkt, especially here it makes sense to buy your food among the delicacies at the market and then eat in the beer garden.
Other well-known beer gardens are the Chinese Tower (easy to reach from Schwabing) and the Seehaus in the English Garden, the Augustiner Garten in Arnulfstrasse or the Hirschgarten beer garden, the largest in Munich.
There is also a small Beer garden in Olympia Park, called Olympia Alm. https://maps.app.goo.gl/NbzUnY1gHDh7wyZUA
