Answer: 
To restart the unity-panel-service, just kill it:

```
killall unity-panel-service

```

If for whatever reason it's not running at all, you can start it via

```
/usr/lib/unity/unity-panel-service

```
To do the same on Unity2d type

```
killall unity-2d-panel

```

or, if just the application launcher on the left fails, type

```
killall unity-2d-launcher

```
